How to unlock the Unbreakable achievement in Drake Hollow - Definitive Guide
Since there seems to be some confusion with people not actually watching the video in the other solution, I'll put in text here:
If you die, just quit. Delete any save created after your death, including the autosave usually made when you quit. Revert to an older save. As long as you never play a save after a death, you'll be good to go.
Pro tip: create a manual save any time you start on a new island. If you do die, which is a lot more frequent in early stages, you won't get set too far back.
Also, Vampiric drakes go a looooong way for longevity.
